Industrial Textile Double Warp Alternating Yarn Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing industrial textiles used as conveyor fabrics require time-consuming silicon stripe treatments for extra grip, which occupy labor and space, and existing solutions do not effectively balance friction and wear resistance.
Innovation Solution
An industrial textile with a double warp structure and alternating yarn diameters in the weft, forming a coarse textured surface for high friction and a smooth surface for wear resistance, eliminating the need for silicon stripes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If silicon stripe treatment is applied to increase grip, then friction and carrying capability are improved, but production time and labor requirements increase significantly
Solution Approach 1:
The patent applies local quality by creating alternating raised and recessed zones directly in the conveyor fabric structure itself. The raised zones provide localized high-friction areas for grip, while recessed zones provide low-friction areas, eliminating the need for separate silicon stripe treatments and reducing production time.
Solution Approach 2:
The conveyor fabric is segmented into alternating raised and recessed zones along the cross-machine direction. This segmentation creates distinct functional areas within the fabric structure that provide both high and low friction zones, replacing the need for additional silicon stripe applications.
2Force
If silicon stripe treatment is applied to increase grip, then friction and carrying capability are improved, but floor space requirements increase during drying
Solution Approach 1:
The patent integrates both high-friction and low-friction characteristics directly into the fabric structure through raised and recessed zones. This eliminates the need for separate silicon stripe materials and their associated drying space requirements, as the friction properties are inherent to the fabric's physical structure.
3Force
If a coarse surface texture is created for high friction, then grip and carrying capability are improved, but wear resistance may be compromised
Solution Approach 1:
The patent applies local quality by creating raised zones with coarse surface texture for high friction and grip, while maintaining separate recessed zones that provide a smoother, more wear-resistant surface. This spatial differentiation allows the fabric to simultaneously achieve both high grip capability and maintained wear resistance.
Solution Approach 2:
The fabric surface is segmented into alternating raised and recessed zones, where the raised zones provide the coarse texture needed for friction and grip, while the recessed zones provide a protected, smoother surface that maintains wear resistance. This segmentation allows both contradictory requirements to be satisfied in different locations.

AI summary
An industrial textile has a double warp. Yarns (111, 112) of a first warp and yarns (131, 132, 133, 134) of a weft are bonded to each other according to a first predetermined pattern, and yarns (121, 122) of a second warp and the yarns (131, 132, 133, 134) of the weft are bonded to each other according to a second predetermined pattern. The first predetermined pattern and the second predetermined pattern form a textile structure, which includes the yarns (131, 132) of the weft on a first level (L1) and the yarns (133, 134) of the weft on a second level (L2). The yarns of the weft having smaller diameter are configured to alternate with yarns of the weft having a larger diameter on the first level (L1).
